Questions and Answers

What does it mean when an object is said to be at rest?

  • The object has zero velocity relative to some reference point. (correct)
  • The object is in a state of constant acceleration.
  • The object is moving at a velocity of 65 MPH.
  • The object is not affected by any external forces.

    • Which statement about acceleration is true?

  • Acceleration has no effect on an object's state of motion.
  • Acceleration involves a change in velocity. (correct)
  • Negative acceleration results in the velocity remaining constant.
  • Positive acceleration occurs when an object decreases its velocity.

    • What is the primary factor responsible for causing motion in objects?

  • Velocity
  • Friction
  • Acceleration
  • Force (correct)

    • How do balanced forces affect the motion of an object?
